Right triangles must follow the pythagorean theorem, so a^2+b^2=c^2.
Let's find a^2 and b^2 by squaring the first 2 side lengths.
(x^2-1)^2= x^4-2x^2+1
(2x)^2= 4x^2
Then add the two to find c^2
x^4+ 2x^2 +1= c^2
Root both sides
x^2+1=c
Since the side lengths can be plugged into the pythagorean theorem, the side lengths must represent a right triangle.
Hope this helps!

Answer: √32
Step-by-step explanation: so the displacement is north 4 and west 4 and it becomes a right triangle so the hypotenuse is the distance for segment AB
So Drawn out should like straight lines up,down,left,and right. So east is positive while west is negative same for North(+) and South(-)
I recommend sticking with 2 directions first. Starting with north and south right. First you go south 1 mile but then you go north 5miles in math terms
-1+5=4 or down one is one less than 5
Same for east and west. 3+-7 = -4
So we went positive 4 miles up and 4miles to the left
So (-4)^2+4^2= hypotenuse or AB segment in this case
23, 710, 23, 751, 23, 715 Least to greatest
23, 23, 23, 710, 715, 751
Answer:
0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: It weighs 2 lbs or more
Event B: Delivered by UPS
15% of the packages that are delivered by UPS weighs 2 lbs or more.
This means that 
More than 2 lbs:
15% of 20%(UPS)
93% of 80%(Not delivered by UPS). So
a. What is the probability that a package is delivered by UPS if it weighs 2 lbs or more
0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more
